Maybe it's from all those childhood days of watching Mr. Ed talking to Wilbur through the top half of his stable door. Whatever it is, one thing is for sure: Americans have a fondness for the Dutch door.

A Pet Door That Makes Sense. The patio door conversion kit by Pet Door Guys is a sensibly designed, custom built, weather-tight panel that fits your existing sliding glass door. While the pet door keeps the weather out, you still have full use of the sliding door, latch and screen. Pets love the freedom. And so will you.

Pet Door FAQs

How big should the opening be?

The pet opening should allow your pet to pass through comfortably. The chart below has opening flap dimensions. If in doubt, create a cardboard opening for your pet to step through using the opening sizes noted below.

How low to the floor should the opening be?

If you have several pets, it should accommodate the smallest pet's ability to see through. With larger pets, keep in mind an appropriate "rise" that will allow for ease of use now as well as in the future as they grow older and slow down with age. As noted above, rise plus opening height should total 1"-2" above the tallest pets back. Don't be afraid to order a larger (taller opening) door if you need low rise (step over) and additional height for clearance.

How high should the pet opening be?

You will want the top of the pet opening to be approximately 1"-2" above the high point of the tallest pet's back. This will reduce wear on the flap. Example: a medium pet door with a minimum rise of 6" added to the opening height of 11" will total approximately 17". This combination will work well for pets with a shoulder height of 16" or less.
